Ley Line

Ley Lines are bands of magical energy that undulate across the globe. They are caused by the interaction of Toril's magic field and the magical flows from the Farie. They have also been known to join places of great magical power, like nodes, but these can be of a temporary nature. Ley Lines are classified as minor and major depending on their width and length. There are many minor Lines but only a few dozen major Lines.
